Can someone point me at a guide on performance monitoring and capacity management of an Apache web farm? Other questions suggest some tools, but I'm also interested in understanding what the various performance parameters are, how to tweak them, tradeoffs among the configuration settings etc.
The web farm is mostly a reverse proxy for a weblogic tier, using the weblogic wlproxy for load balancing across the weblogic servers. It terminates SSL connections, but otherwise does very little other than pass things to and from weblogic. A (hardware) loadbalancer fronts the web servers.
I have already seen this :)
